diamond cutter is made of diamond saws
The diamond tool machining brittle materials There are a variety of diamond saws and diamond grinding wheel, despite the application of various tools and processing characteristics are different, but the wear mechanisms are roughly the same, diamond grade, content, particle size, binder and diamond shape matching and tools related factors with the  diamond discs tool itself is an important factor affecting tool wear.
Typically diamond content, low power consumption is also low; however diamond content is too low, the macro may be exacerbated by fragmentation, resulting in a lack of blade height, so that power consumption actually increased; diamond content is high, the power consumption increases, leading diamond shedding tool-resistant grindability decreased. If the diamond grade higher in the case of lower levels, and its crystal structure was still intact higher nodal high abrasion resistance, low power consumption, but the diamond grade should be selected to match with the binding agent. Wu Jian and other analysis of diamond quality dispersion of the impact of the sawing process, pointing out that the wear resistance of diamond quality is good, must require binding agent also has good wear resistance, the only way to give full play to the role of high-quality diamond. While the low-quality diamond, due  9 inch saw blade to its compressive strength and impact resistance are poor, even easier cutting also occurs when the mineral composition of obvious wear and broken, especially difficult in the face of the cutting portion, generally occurs macro broken cutting ability and lose, then the wear resistance of the binding agent is required to be relatively low, in order to ensure there is enough of the diamond blade height. At the same time, should try to reduce the hole saw blades  quality of the diamond dispersion. By analyzing vitrified diamond grinding wheel spindle machining Sapphire deformation process (grinding required by deformation indicates normal load changes) and found that it becomes a periodic change, indicating wheel with self sharpness because vitrified grinding wheels wear of the material is brittle fracture binding agent, which will quickly a new abrasive grains. The metal and resin bonded grinding wheel wear is mainly friction and wear and abrasion. YCFu grinding wheel is given such an optimization model, through this model, according to the processing requirements and parameters to optimize grinding wheel (including grain size, concentration, stretched out rate and effective abrasive space), but also according to wheel optimization of grinding parameters and processing requirements (including grinding depth, wheel speed and workpiece feed rate). In addition there are many scholars have conducted a research in this area.
